I’ve yet to hear anyone with a MBA praise that “incredible thinness.” That’s the sort of thing pundits gush about. No one complains about “the deletion of non-necessary features,” but that’s certainly not a factor that wows anyone. It’d be like being wowed by a new car that replaces a full-sized spare tire with one of the tiny, temporary ones. Those dropped features are tolerable because they doesn’t affect how people use their MBA.

What they do praise is the quick boot time and the responsiveness. That’s where the MBA really hit a home run and why it’s selling. Of course, for about $900 less, I got the same results by adding a OWC SSD to my MacBook. As I tell friends, for $900 I’ll lug around a couple of extra pounds.

Pixel densities will grow and stop at just over 300 ppi as the Mac OS underneath moves toward resolution independence.

Desktop Mac will get even larger interaction surfaces to pair with the mouse. There may be some attempt to introduce 3D but not very quickly.

If yields go up and costs go down the hard drive will disappear from the MacBook Pro line as well.
